My girlfriend isolates herself from me
I don't know if I have a problem with my girlfriend.
She's a good girlfriend. We don't have fights over futile things, jealousy or usual things of couples. She's the type who prefers to sit down to talk when something happens that she doesn't like, she hates fighting where one yells at the other. It was something I learned from her and today I also prefer to talk. But I feel that somehow we are not compatible because she doesn't like to be with me, she seems to get tired. And it's not like she gives signs that she doesn't like me, she's affectionate, careful, pays attention to what I like and don't like. But she really likes to be alone, so sometimes when we spend a lot of time together out of nowhere she starts to get more distant, as if she were tired of talking to me. I haven't talked to her yet because it might be something in my head. She doesn't give me reasons to distrust, she is very vocal about what she feels for me and in general she is my ideal type in everything, sensitive, intelligent, calm, funny. She's also the first girlfriend who doesn't think it's the end of the world I want to have friends, she even suggests that I go out with friends, even travel only with guys, because she herself says it's something she likes to do. Because I'm a little traumatized, I already think there's something wrong there, even more so when I relate it to the fact that she isolates herself sometimes. I like her very much and wanted to marry her, but I don't know if these thoughts of mine will only get worse in the long run.
